I have a system with an IPO 403 one end and a 406 the other
trying to get 5 calls working over the vpn, i have cisco 1751 routers at each end with the following set up (see router extract)
we are getting calls that people cant hear each other at the other IPO (internal IPO to IPO calls)
my DSCP set to 46 in the IPO's and using G.729(a)8k codec
The Carrier has confirmed QOS is setup on their side and the Voice Class isnt dropping any packets
Any ideas where to start?
